What's The Name Of That Song? Lyrics

La-de-da-de-dum, La-de-da-de-dum, What's the name of that song?
La-de-da-de-dum, La-de-da-de-dum, What's the name of that song?
It goes la-de-da-de-dum, La-de-da-de-dum, Something something birds.
La-de-da-de-dum, La-de-da-dee, I wish I remembered the words.
La-de-da-de-dum, La-de-da-de-dum, What's the name of that song?
La-de-da-de-dum, La-de-da-de-dum, I'd like to sing right along!
I've heard it said, With words and music A fellow can't go wrong.
So la-de-da-de-dum, La-de-da-de-dum, What's the name of that song?
La-de-da-de-dum, La-de-da-de-dum, What's the name of that song?
La-de-da-de-dum, La-de-da-de-dum, We need the name of that song!
It goes la-de-da-de-dum, La-de-da-de-dum, Something, something nice. [ From: http://www.metrolyrics.com/whats-the-name-of-that-song-lyrics-sesame-street.html ]
La-de-da-de-dum, La-de-da-dee, I think it repeats itself twice!
La-de-da-de-dum, La-de-da-de-dum, What's the name of that song?
La-de-da-de-dum, La-de-da-dee, I know the name of that song!
It's called--now wait, I think I got it! Oh, no--I must be wrong--
So la-de-da-de-dum, La-de-da-de-dum, What's the name of that song?
(Honkers) Honk-ee-honk-ee-honk, honk-ee-honk-ee-honk (Oscar-annoyed) What's the name of that song? (All) La-de-da-de-dum, La-de-da-de (Oscar) They keep on singing that song
They go La-de-da-de-dum, La-de-da-de-dum La-de-da-de-dum, La-de-da-de-dum, La-de-da-de-dum, They start it all over again.
La-de-da-de-dum, La-de-da-de-dum (Gordon) Something shining above. (two-headed monsters sing some unintelligible words that end with something that rhymes with "above") We can't help singing La-de-da-de-dum Loud and clear and strong.
But La-de-da-de-dum, La-de-da-de-dum La-de-da-de-dum, La-de-da-de-dum La-de-da-de-dum, Laaaaaaaaaaaa!
What IS the name of that song?
